Accounting Software E-Commerce Integration 2026: Logo, Mikro, Parasut and Uyumsoft Compared

The 2026 Turkish Accounting Software Landscape at a Glance

No Western European country has a domestic accounting stack as concentrated as Turkey's. Four vendors cover well over 90% of business invoicing volume; the rest are SaaS challengers or vertical specialists. The cards below summarise the six platforms covered in this guide — keep them nearby as you read each deep-dive section.

1. Logo Yazilim — Turkey's Largest Software House

Logo at a Glance

Logo Yazilim is, by almost every metric, the centre of gravity of Turkish business software. Founded in 1984 in Istanbul by Tugrul Tekbulut, listed on Borsa Istanbul as BIST:LOGO since 2000, Logo serves more than 250,000 customers across Turkey, Romania and selected MEA markets. By 2026 the group's flagship products — Tiger 3 (mid-market ERP), Wings (cloud ERP), Netsis Wings (enterprise ERP, acquired with Netsis in 2012) and j-Platform (large enterprise) — together hold roughly 40% of the Turkish mid-market ERP segment, comfortably the largest single share.

The Logo umbrella also includes Logo Mind (analytics), Logo eIK (HR & payroll), Logo Diva (vertical retail), Logo Connect (middleware) and Logo eFatura — Logo's own GIB Special Integrator service. For sellers this is a relevant detail: if you already use any Logo product, the cheapest way to get e-Invoice running is usually to enable Logo eFatura inside the same suite rather than contracting a separate integrator.

Logo's importance to Turkish e-commerce stems from a simple fact: a very large share of mid-market suppliers, importers and distributors invoice on Logo Tiger 3 or Netsis. If you are sourcing wholesale and reselling on Trendyol or Hepsiburada, your supplier's invoices almost certainly hit your inbox as Logo-issued e-Invoices.

Tiger 3 — The Workhorse Mid-Market ERP

Tiger 3 is Logo's mid-market ERP and the single most widely deployed accounting platform among Turkish SMEs with 20–500 employees. The product covers general ledger, accounts receivable / payable, inventory, multi-warehouse, production planning, payroll integration and a full e-Invoice / e-Archive / e-Waybill / e-Self-Employment Receipt (e-SMM) stack. It runs on Microsoft SQL Server, deployed on-premise or in a private cloud, and is sold via a network of 600+ certified Logo Business Partners.

For e-commerce sellers the relevant Tiger 3 modules are: Stok (multi-warehouse inventory), Sevkiyat (shipment management), Fatura (invoicing), e-Donusum (e-Transformation hub — GIB connectivity) and the optional Logo Mind Insight for reporting.

Logo Wings — The Cloud Move

Logo Wings, launched in 2017 and substantially modernised in 2024, is Logo's cloud-native ERP. Wings is positioned as a successor to Tiger 3 for new customers who don't want to manage SQL Server licences and on-prem servers. By 2026 Wings carries close to 30,000 active customers and is Logo's fastest-growing product line. The feature parity with Tiger 3 is close but not complete — Wings is preferable for e-commerce sellers who don't have legacy ERP integrations to migrate.

Netsis Wings — The Enterprise Tier

Netsis Wings, derived from the Netsis ERP Logo acquired in 2012, is the choice for larger sellers (typically TRY 200M+ annual revenue, multi-company groups, multi-currency export operations). Netsis Wings handles consolidated reporting, IFRS, tax-free zones, e-Mustahsil (agricultural receipt) and the full e-Document spectrum. Pricing is significantly higher than Tiger 3 and the implementation projects run 3–9 months with a partner.

Logo Pricing Bands 2026

Logo does not publish public list pricing — every quote runs through a Logo Business Partner — but typical 2026 ranges for an e-commerce-ready configuration are:

Logo + Marketplaces — How Zunapro Wires It

The standard Trendyol-to-Logo flow looks like this: order is created on Trendyol, Zunapro picks it up via the Trendyol Marketplace API within 30 seconds, normalises the order payload, writes a Satis Faturasi (Sales Invoice) directly into the Logo SQL database using Logo's "Akilli Veri Aktarim" gateway, then triggers the e-Archive or e-Invoice flow via Logo eFatura — all before the warehouse picker even sees the order. The same flow works for Hepsiburada, N11, Ciceksepeti, Amazon TR and Pazarama in parallel; Zunapro deduplicates by SKU + marketplace order ID so the same physical order is never invoiced twice.

2. Mikro Yazilim — The Retail and Chain-Store Champion

From Ankara DOS Roots to Modern Retail

Mikro Yazilim was founded in 1986 in Ankara by Vahap Munyar and is, alongside Logo, the second pillar of Turkish business software. While Logo went mid-market and enterprise, Mikro built deep roots in retail, chain stores, restaurants and FMCG distribution. By 2026 Mikro serves 180,000+ active customers and its RKS POS system runs in well over 35,000 store lanes across Turkey — supermarkets, fashion retailers, electronics chains, pharmacies and quick-service restaurants.

The Mikro product line in 2026 is:

• Mikro Fly — flagship ERP for medium-sized companies (the spiritual equivalent of Logo Tiger 3)
• Mikro Jump — entry-level ERP for small businesses (50–500 SKUs, single warehouse)
• RKS — retail point-of-sale system, the de facto standard in Turkish chain retail
• Mikrogrand — Mikro's cloud SaaS, launched 2021, positioned against Parasut
• Mikro e-Donusum — the e-Document bundle (e-Invoice, e-Archive, e-Waybill, e-SMM)

Mikro Fly — Retail-First ERP

Mikro Fly dominates Turkish multi-store retail. Its differentiator versus Logo Tiger 3 is the depth of the store-management module: per-branch stock policies, in-store transfer documents, branch-level cash management, integrated promotions, shrinkage tracking, and a battle-tested connection to RKS POS lanes. Fashion sellers running both physical stores and Trendyol / Hepsiburada listings overwhelmingly choose Mikro Fly over Logo because the same SKU master serves the store cashier and the marketplace listing without translation.

Mikrogrand — The Cloud Bridge

Mikrogrand, launched 2021, is Mikro's SaaS answer to Parasut. It is intentionally less feature-rich than Mikro Fly because it targets micro-businesses (1–5 employees, single warehouse, modest invoice volume). The strategic value for Mikro is the upgrade path: a Mikrogrand customer can graduate to Mikro Fly without re-keying suppliers, customers or chart of accounts. Pricing starts at roughly TRY 449 / month per user in 2026.

Mikro Pricing Bands 2026

e-Document add-on is typically licensed separately, at roughly TRY 0.18–0.35 per e-Invoice depending on volume and which Special Integrator the customer chooses.

Mikro + Marketplaces — RKS-Aware Integration

Zunapro's Mikro connector is RKS-aware: when an order arrives from Trendyol or Hepsiburada, Zunapro checks the warehouse policy — does the SKU ship from the e-commerce warehouse, or is it a "ship from store" SKU served by an RKS lane? If the latter, the Mikro transfer document is generated against the correct branch, and the e-Archive is issued from that branch's tax identity. For multi-store retailers this is the single biggest practical advantage versus a generic "API to one warehouse" connector.

3. Parasut — The SaaS-First SME Leader

From Bootstrap Startup to PayU-Backed Platform

Parasut was founded in 2014 in Istanbul by Mete Cakmakci and a small team of ex-bankers and developers. The pitch was simple: every Turkish accounting product at the time was either a heavy Windows ERP (Logo, Mikro) or a paper-and-Excel manual process. Parasut delivered a clean web app with a developer-friendly REST API, native e-Invoice integration via Foriba, and a per-month subscription that started at a fraction of an entry-level Logo licence. By 2020 Iyzico (and through it PayU and Prosus) acquired Parasut, giving the platform deep payments-data integration and a route into broader fintech bundles. In 2026 Parasut serves 250,000+ Turkish SMEs and is the most-used accounting platform among solopreneurs and SaaS-first e-commerce sellers.

Why E-Commerce Sellers Love Parasut

• Native REST API — fully documented, OAuth 2.0, with a public sandbox
• 200+ pre-built integrations — Trendyol, Hepsiburada, N11, Ciceksepeti, Shopify, IdeaSoft, WooCommerce, Iyzico, PayTR, Stripe, Sipay, Param
• Built-in e-Invoice / e-Archive — issued through Foriba (now Sovos) Special Integrator, no separate contract
• Mobile-first UX — a finance team can manage their entire month-end from a phone
• Transparent pricing — published tiers from TRY 449 / month upward, no licensing surprises

Parasut Pricing Bands 2026

e-Invoice / e-Archive per-document fees pass through Foriba pricing (TRY 0.15–0.40 per document depending on volume).

Where Parasut Hits Its Ceiling

Parasut is exceptional up to about 15,000 monthly orders. Above that, three structural limits start to bite: API rate limits become painful even on Enterprise, the chart-of-accounts customisation is shallow compared with Logo / Mikro, and consolidated multi-company reporting (mandatory for groups with 3+ entities) is not first-class. Sellers in that bracket typically graduate to Logo Tiger 3 or Uyumsoft Vega. The good news: Zunapro keeps the same marketplace connectors in place during the migration, so the only thing that changes is the accounting back-end.

4. Uyumsoft — Enterprise ERP + GIB Special Integrator

Two Businesses in One

Uyumsoft was founded in 1996 in Istanbul and is unusual in the Turkish market because it is simultaneously a serious enterprise ERP vendor and one of the four largest GIB-licensed Special Integrators. By 2026 Uyumsoft serves more than 40,000 ERP customers (Vega, NX, NetGenel) and processes a meaningful share of all Turkish e-Invoices through its Uyumsoft Ozel Entegrator service. The vertically-integrated model means sellers using Uyumsoft ERP do not pay a third-party integrator margin on each invoice — the e-Document fees and the ERP licence are part of one bundle.

Uyumsoft Vega — The Mid-to-Enterprise ERP

Vega is Uyumsoft's mid-market ERP, broadly comparable to Logo Tiger 3 and Mikro Fly, with particular strength in manufacturing, wholesale distribution and import-heavy commerce. The native e-commerce module supports Trendyol, Hepsiburada, N11, Ciceksepeti and Amazon TR out of the box, plus a generic REST adapter for own-shop platforms (IdeaSoft, Shopify, custom). Vega is sold via Uyumsoft's direct sales team and a network of solution partners; the typical implementation runs 6–14 weeks.

Uyumsoft NX — The Enterprise Tier

NX is Uyumsoft's enterprise ERP, used by larger industrial groups, multi-company holdings and exporters. It includes IFRS-aligned consolidation, multi-currency, transfer pricing, advanced manufacturing planning and full e-Document compliance. NX competes with Logo Netsis Wings and SAP Business One at the lower end of the enterprise market.

5. Nebim, Bizmu and the Vertical Specialists

Nebim V3 — The Fashion ERP

Nebim was founded in 1987 and is the dominant ERP in Turkish fashion retail. Its flagship Nebim V3 runs the back-office for LC Waikiki, Mavi, Defacto, Boyner, Koton and most of the country's top apparel chains. For pure-play marketplace sellers Nebim is overkill, but for fashion brands that operate physical stores plus a Trendyol / Trendyol International / Hepsiburada presence, Nebim is frequently mandatory: the assortment planning, size-curve management and seasonal-collection workflows are the gold standard of the industry. Zunapro's Nebim connector reads the Nebim "Magaza" (store) hierarchy directly so that the marketplace stock view matches what the planner sees in Nebim.

Bizmu — Solopreneur SaaS

Bizmu, launched in 2017, is positioned below Parasut for the very small end of the market — freelancers, solopreneur Etsy / Shopify sellers, single-person Trendyol stores. Pricing starts at TRY 199 / month with e-Archive included through QNB eFinans. The trade-off is the limited API and modest customer-support depth; sellers grow out of Bizmu around 500 invoices / month.

Side-by-Side Comparison Table 2026 — All Six Platforms

The single most useful artefact for choosing your accounting back-end is a side-by-side comparison. The table below summarises 2026 pricing, target segment and the GIB Special Integrator each platform partners with.

Platform	Sweet Spot	Entry Pricing	API / Integration	GIB Special Integrator
Logo Tiger 3	Mid-market 20–500 employees	₺28K – ₺75K licence	Logo Connect · SQL gateway · ODBC	Logo eFatura (in-house)
Mikro Fly	Retail chains, multi-store	₺55K – ₺180K licence	Mikro DB · RKS bridge · SOAP	Choice of Foriba / Uyumsoft / QNB
Parasut	SaaS-first SMEs, up to ~15K orders/mo	₺449 – ₺2.8K /mo	Native REST API · OAuth 2.0	Foriba (Sovos)
Uyumsoft Vega	Manufacturing + distribution mid-market	₺48K – ₺160K licence	Uyumsoft API · SQL · native e-commerce module	Uyumsoft (in-house)
Nebim V3	Fashion + footwear chain retail	Project pricing	Nebim API · in-store + marketplace	Choice of Foriba / Uyumsoft
Bizmu	Solopreneurs, <500 invoices/mo	From ₺199 /mo	Light REST API	QNB eFinans

Reading the table: Parasut and Bizmu are the only two true SaaS products. Logo and Mikro are licence-plus-support models, with cloud variants (Wings, Mikrogrand) running in parallel. Uyumsoft is the only ERP that is also its own GIB Special Integrator, removing one vendor from the contract chain. Nebim is the fashion vertical — outstanding inside its niche, outside the scope for generic e-commerce sellers.

GIB Compliance 2026 — e-Invoice, e-Archive, e-Waybill

The Revenue Administration (GIB) and the e-Donusum Programme

The Revenue Administration — Gelir Idaresi Baskanligi (GIB) — runs Turkey's e-Document programme under the umbrella name e-Donusum (e-Transformation). Launched in 2010 with the e-Defter (e-Ledger) pilot, the programme has been progressively widened to cover e-Invoice (2014), e-Archive (2016), e-Waybill (2019), e-SMM (Self-Employment Receipt, 2018), e-Mustahsil (Agricultural Receipt, 2018) and several niche documents. Turkey is, alongside Italy and South Korea, one of the most digitally mature tax administrations in the world.

e-Fatura vs e-Arsiv — The Critical B2B / B2C Split

This is the single most important distinction for an e-commerce seller to internalise:

• e-Fatura (e-Invoice) — the recipient is a GIB-registered taxpayer (B2B). The invoice flows through the closed GIB e-Fatura system, the recipient receives a digital notification, can accept or reject the invoice, and the transaction is fully visible to GIB on both sides.
• e-Arsiv (e-Archive) — the recipient is an end consumer or a non-e-Fatura business (B2C and small B2B). The invoice is generated electronically by the seller, the seller stores it for the legal retention period, and a daily summary report is submitted to GIB. The recipient receives the PDF by email or downloads it from a portal.

Marketplace sellers have an obvious operational implication: roughly 92–96% of Trendyol / Hepsiburada / N11 / Amazon TR orders are B2C and therefore require e-Archive. The remaining 4–8% are B2B (resellers, small businesses) and require e-Invoice. Zunapro classifies each marketplace order automatically by querying the buyer's tax identifier against the GIB e-Fatura participant list.

2026 Thresholds — Who Is Now in Scope

• e-Invoice — mandatory for all taxpayers with annual gross sales above TRY 3 million (further reduced from 5M in 2026)
• e-Archive — mandatory for all sellers active on marketplaces and for any seller with gross sales above TRY 500,000
• e-Waybill (e-Irsaliye) — mandatory for taxpayers in scope of e-Invoice and for all goods movements above TRY 50,000 per document
• e-Defter (e-Ledger) — mandatory for e-Invoice taxpayers, monthly upload to GIB
• e-Mustahsil — mandatory for agricultural product buyers from individual farmers

Penalties for Non-Compliance

Penalties under the VUK (Vergi Usul Kanunu — Tax Procedure Law) are not symbolic. A missing e-Invoice can attract a "ozel usulsuzluk" penalty per document, capped per taxpayer per year but easily reaching TRY 100,000–500,000 for a high-volume marketplace seller who falls out of compliance for a single month. Late e-Waybill issuance attracts a separate per-shipment fine, and reading the daily e-Archive batch as "submitted on time" is enforced down to the timestamp.

GIB Special Integrators 2026 — Choosing Your e-Invoice Provider

What a Special Integrator Does

A Special Integrator (Ozel Entegrator) is a GIB-licensed company authorised to send and receive e-Invoices on behalf of taxpayers. The alternative — a "Direct Integration" (Dogrudan Entegrasyon) — requires the taxpayer to maintain its own GIB-certified infrastructure, which is impractical for any seller below the very largest enterprise scale. So in practice, virtually every marketplace seller in Turkey operates through one of the four large Special Integrators.

The Big Four in 2026

• Foriba — acquired by Sovos in 2019, the international tax-tech leader. Foriba is the integrator behind Parasut, many Logo customers and a large slice of the SaaS market. Strongest in API quality and SLA, slightly more expensive per document.
• Uyumsoft Ozel Entegrator — Uyumsoft's own integrator service. The natural choice for Uyumsoft ERP customers because the bundle eliminates a separate vendor; aggressive volume pricing.
• QNB eFinans — operated by QNB Finansbank, integrated with QNB merchant services. Strong on the SME and freelance segment, the default integrator behind Bizmu and many independent SaaS apps.
• Izibiz — independent integrator, strong reputation in mid-market, used by many Logo and Mikro customers as an alternative to Logo eFatura.

Per-Document Pricing 2026

All four integrators publish volume-tiered pricing roughly in the same band:

For a seller doing 10,000 marketplace orders / month, the integrator bill works out at roughly TRY 1,800–2,500 / month — a rounding error compared with marketplace commission, but a real line in the P&L.

Marketplaces and Accounting — The 2026 Connectivity Map

Trendyol — The 800-Pound Gorilla

Trendyol is the largest Turkish marketplace by some margin, with more than 30M active customers and an outsized share of the country's online retail GMV. From an accounting perspective, every Trendyol order needs either an e-Invoice (B2B) or e-Archive (B2C), issued within 7 days of the despatch event. Trendyol provides an XML feed of buyer tax identifiers via its Marketplace API; Zunapro reads it, classifies B2B vs B2C and routes the invoice through Logo / Mikro / Parasut / Uyumsoft accordingly.

Hepsiburada — The B2B-Heavy Marketplace

Hepsiburada (NASDAQ:HEPS) skews more B2B than Trendyol — its electronics, IT and home-appliance categories see a higher share of business buyers (reseller, SOHO, small office). For sellers active on Hepsiburada, the share of e-Invoice (versus e-Archive) is typically 10–15%, double the Trendyol average. The accounting integration is otherwise identical; the only practical difference is that the e-Invoice rejection rate is also higher, so the seller needs a clean process for handling "reddedilen fatura" notifications.

N11, Ciceksepeti, Amazon TR, Pazarama

• N11 — owned by Dogus Holding · classic broad marketplace · standard e-Archive flow
• Ciceksepeti — flowers + gifting · same-day fulfilment · time-sensitive e-Archive issuance
• Amazon TR — VAT-OSS-relevant for sellers shipping cross-border · separate e-Invoice flow for FBA returns
• Pazarama — Mubadala-backed challenger · growing rapidly · same accounting stack as the others

How Zunapro Orchestrates the Whole Stack

Behind the scenes, Zunapro maintains a normalised order schema with the marketplace as a "source" field and the accounting platform as a "destination" field. The same Trendyol order can therefore flow into a Logo Tiger 3 instance, a Parasut tenant, a Mikro Fly database or a Uyumsoft Vega installation without changing the operator's day-to-day workflow. Stock is synchronised in the opposite direction: when the accounting platform records a stock adjustment, the new quantity is propagated back to every marketplace within 30 seconds, preventing oversells.

Migration Playbook 2026 — Switching Between Platforms

Parasut → Logo Tiger 3 (The Growth Migration)

The most common Turkish accounting migration in 2026 is Parasut → Logo Tiger 3. The trigger is almost always volume: the seller crosses ~10,000 orders / month, hits Parasut's chart-of-accounts limits, or needs multi-company consolidation. The migration project takes 6–10 weeks with a Logo partner; Zunapro keeps the marketplace connections live throughout the cutover so there is no order-loss window.

Mikro Jump → Mikro Fly (The Vertical Migration)

Retail-first sellers who started on Mikro Jump frequently upgrade to Mikro Fly as their second / third / fourth store opens. Because both products share the underlying Mikro database schema, the migration is dramatically simpler than a cross-vendor move — typically 2–3 weeks, no marketplace downtime.

Custom ERP → Uyumsoft Vega (The Consolidation Migration)

Mid-market manufacturers with a legacy custom ERP often consolidate onto Uyumsoft Vega when they add an e-commerce arm. The migration's hard part is rarely the accounting data — it is harmonising the SKU master between the ERP, the warehouse and the marketplaces. Zunapro's SKU normalisation engine is specifically built for this scenario.

Logo → Mikro (Or Vice Versa) — The Rare Cross-Move

Cross-vendor moves between Logo and Mikro are rare and expensive: the SQL schemas are different, the chart of accounts maps one-to-one only at the very top level, and historical e-Documents typically cannot be re-issued from the new platform. The 2026 rule of thumb: migrate only if there is a strategic business reason — a private-equity acquisition, a vertical change (warehouse-only seller adds physical stores), or a multi-year cost case. Otherwise, keep the existing ERP and add Zunapro as the marketplace orchestration layer.

How to Connect Your Accounting Software — 2026 Step-by-Step

1. Choose Your Accounting Stack (Decision Tree)

• SaaS-first, <15K orders/month → Parasut
• Solopreneur, <500 invoices/month → Bizmu (or Parasut Starter)
• Multi-store retail chain → Mikro Fly + RKS
• Mid-market, 20–500 employees, mixed B2B/B2C → Logo Tiger 3
• Manufacturing + import + multi-company → Uyumsoft Vega
• Fashion / footwear chain → Nebim V3
• Enterprise, IFRS, multi-country → Logo Netsis Wings or Uyumsoft NX

2. Confirm Your GIB Status

Before connecting, verify your e-Invoice / e-Archive scope against GIB's online query (the "Kullanici Listesi" lookup on the e-Fatura portal). Check three things:

• Are you registered for e-Fatura? (Required if annual gross > TRY 3M)
• Are you registered for e-Arsiv? (Required for marketplace sellers and gross > TRY 500K)
• Are you registered for e-Defter? (Required if you are in e-Invoice scope)

If any of the three is missing, your accounting partner (mali musavir) or your Special Integrator can complete the registration in 1–3 business days.

3. Pick (or Confirm) Your Special Integrator

If you use Parasut, your integrator is automatically Foriba. If you use Uyumsoft ERP, it is Uyumsoft. If you use Logo, you can choose either Logo eFatura (in-house) or contract Izibiz / Foriba. If you use Mikro, you choose any of the four. The integrator contract is signed directly between you and the integrator; Zunapro routes documents through whichever you have chosen.

4. Connect via Zunapro (15-Minute Integration)

1. Sign in to Zunapro and open the Turkey → Accounting module
2. Select your accounting platform from the catalogue (Logo, Mikro, Parasut, Uyumsoft, Nebim, Bizmu, plus international ERPs)
3. Paste the connection details — SQL connection string for Logo / Mikro / Uyumsoft, OAuth token for Parasut, API key for Bizmu
4. Map warehouses and tax identities — Zunapro's wizard auto-suggests mappings; confirm with a few clicks
5. Enable marketplace connectors — single toggle each for Trendyol, Hepsiburada, N11, Ciceksepeti, Amazon TR, Pazarama
6. Run a test invoice — a single end-to-end order is processed in sandbox to verify the round trip
7. Go live — the first production sync completes within roughly 15 minutes for a 1,000-SKU catalogue
