ERP and Accounting Software Integration
ERP accounting software integration for EU companies running Bulgarian accounting stacks — Microinvest, Aladin, Plus Minus, Business Navigator. We stop double-entry, sync numbering and prepare VAT ledgers automatically before NRA submission.
What the ERP accounting integration includes
A custom bridge between ERP and accounting program in the format the program speaks — REST API where it exists (Microinvest Pro, recent Plus Minus), file-based import (.xml, .csv, .txt) for Aladin and older Business Navigator. No third-party plugin that vanishes next year.
- ✓Automatic invoice transfer — sales and purchases — every invoice flows daily or in real time into the accounting program with counterparty, date, basis, VAT base, rate and ledger entries.
- ✓Numbering synchronization — a single series across ERP and accounting, no duplicates or gaps; credit notes get correct reference numbers automatically.
- ✓Pre-publish validation — VAT-ID checked against the NRA registry, counterparty existence verified; missing data holds the invoice in a pending queue.
- ✓VAT ledger — purchases and sales journals — exact NRA-required fixed-width .txt format, ready for portal upload on the 14th.
- ✓Multi-company structure — shared ERP with separate VAT IDs gets correct per-entity routing.
- ✓Exceptions and unmatched flags — daily report of failed documents on a single screen, not in logs.
- ✓Monthly close and reconciliation — auto monthly diff report between ERP and accounting turnover by account, counterparty and VAT rate.
Who the ERP↔accounting bridge is for
You run an ERP for production and sales, but accounting is outsourced to a firm on Microinvest or Aladin. Integration replaces hand-typing from PDF with a sync feed — and the firm bills you fewer hours.
You sell through your own site, eMAG, Amazon and a physical store. Hundreds of invoices a day collapse into one ERP with correct VAT for intra-EU supplies, OSS and exports.
You have 1-3 in-house accountants on Plus Minus or Business Navigator. They stop typing invoices and work on analysis, control and close — a finance partner for the CEO.
How we build the ERP accounting bridge
The approach is "in the format the accounting program speaks" — API where it exists, fixed-width file import where it does not. We never ask the client to switch accounting software for our integration.
1. Discovery — ERP, accounting program, documents
Day one we sit with finance and IT. We document the accounting program, which documents transfer (invoices, advances, protocols, warehouse slips), frequency and accepted format.
2. Backend — Node.js or .NET middleware
Middleware runs on Node.js (TypeScript) or .NET 8. It reads ERP via REST API, transforms to the accounting schema and writes through API or a watched folder.
3. Reconciliation and monitoring
A nightly cron job compares ERP and accounting turnover and emits a report — count, gross, net, diffs by counterparty and VAT rate. Above threshold (0.50 BGN or 5 invoices) finance gets email and on-call gets Telegram. Silent errors do not exist.
4. Staging base before live
We never push into the production accounting base directly — books have locked annual periods. We run in a copy first for one or two months and cut over on the 1st when reconciliation hits 100%.

Frequently Asked Questions
Which Bulgarian accounting software do you support?
We cover the full Bulgarian landscape — Microinvest (Pro and Light), Aladin, Plus Minus, Business Navigator, AjurL, Azhur-7, plus hybrid SAP Business One and Microsoft Dynamics installs. The approach is always "the format the program speaks" — API where it exists, .xml / .csv / .txt import where it does not. We never ask the client to switch accounting software.
What happens if an invoice has an error?
Broken documents do not enter accounting — the middleware tags them "exception" and surfaces them on a single screen. Typical errors: VAT-ID failing the NRA check, SKU missing from the accounting nomenclature, negative net without a matching credit note, date outside an open period. The accountant fixes the document and the system transfers it next cycle.
How often are invoices synchronized?
Default — every 15 minutes in business hours plus a full nightly sync with reconciliation. If the accounting program cannot take that cadence (Aladin prefers batch) we drop to four daily batches at 09:00, 13:00, 17:00 and 22:00. For e-commerce clients with tens of thousands of monthly documents we run event-driven sync.
How much does ERP accounting software integration cost?
Entry price €2,200 for a standard integration between one ERP and one accounting program with daily sync of sales and purchase invoices and a baseline reconciliation report. Multi-company with 2-5 VAT IDs on a shared ERP — from €3,400. Integration that also includes an automatic NRA-format VAT ledger plus intra-EU supply protocols and OSS — from €4,200. Support and monthly monitoring — €120/month.
