Generate EFT Batch Files for South African Banks
Every Friday your finance team rebuilds a bank file in Excel so hundreds of suppliers get paid. One wrong branch code or hash total and the upload fails, the pay run slips, and you have no clean audit trail for who approved what.
We automate bank file generation from your accounting system so you upload once and pay the batch.
Sound Familiar?
These are the exact issues our clients faced before automating bank file generation:
- Finance rebuilds supplier EFT batch files in Excel every pay run, then re-formats them for the bank portal
- ABSA, FNB, Standard Bank, and Nedbank each reject files for different reasons: hash totals, branch codes, record length
- Refund queues in the CRM are retyped into the bank file by hand, with no link back to the original ticket
- When a batch fails validation, suppliers wait another day while the file is rebuilt from scratch
- Auditors ask who approved which payments, and the only trail is an email thread and a spreadsheet
South African banks still run both ACB flat files and ISO 20022 pain.001. Building either format by hand in Excel is fragile, and a single hash-total or field-length error rejects the whole upload. Automating generation is the reliable path as portals tighten validation.
What Automated Bank File Generation Actually Does
Bills approved → validated EFT batch built → one upload → ledger marked paid. No human rebuilding the file.
Payables Approved
Supplier bills clear in Xero, Sage, or QuickBooks; CRM refunds join the same queue
EFT Batch Generated
System builds the ACB or pain.001 file for your bank, with hash totals and beneficiary checks
Finance Reviews & Uploads
One review, dual auth in the bank portal, single upload for hundreds of payments
Remittance Synced Back
References write back to the ledger and CRM, with a full audit log of the run
Everything You Need for Reliable Bulk EFT
Bank-Specific File Generation
Approved bills and refunds become ABSA, FNB, Standard Bank, or Nedbank upload files in the format your corporate banking portal expects.
ACB and ISO 20022 Support
We generate legacy Bankserv ACB flat files and ISO 20022 pain.001 credit transfers, so you are ready whichever standard your bank requires.
Pre-Upload Validation
Hash totals, branch codes, account lengths, and action dates are checked before the file leaves your systems. Rejects get fixed in minutes, not overnight.
Accounting and CRM Sources
Pull supplier bills from Xero, Sage, or QuickBooks, and customer refunds from your CRM queue, into one controlled pay run.
Full Audit Trail
Every line that enters a batch is logged with who approved it, when it was generated, and which file version went to the bank.
Remittance and Sync-Back
Once the bank accepts the batch, remittance references write back to the ledger and CRM so finance is not chasing proof of payment.

Frequently Asked Questions
Which South African bank formats can you generate?
We generate Bankserv ACB flat files and ISO 20022 pain.001 credit-transfer files for the major corporate portals, including ABSA, FNB, Standard Bank, and Nedbank. If your bank publishes a host-to-host or import specification, we can match it.
Where does the payment data come from?
Most clients pull approved supplier bills from Xero, Sage, QuickBooks, or Pastel. Others also include customer refunds from a CRM queue. We map beneficiary name, account, branch code, amount, and reference from the source of truth so finance is not retyping.
Will this replace our bank's dual-authorisation controls?
No. The integration prepares a validated upload file. Your existing dual-control and authorisation rules in the bank portal stay in place. We add an upstream audit trail for who approved the pay run before the file was generated.
What happens when a file fails bank validation?
Pre-upload checks catch the common failures: wrong record length, missing hash totals, invalid branch codes, and account numbers that do not fit the field. When something still fails at the bank, the error maps back to the specific line so you fix one record, not rebuild the whole spreadsheet.
How long does EFT batch file generation take to set up?
A standard single-bank setup takes 2 to 4 weeks from scoping to go-live. Multi-bank formats, dual ACB and pain.001 support, or CRM refund queues take closer to 4 to 6 weeks, including parallel testing against a live pay run.
How much does automated EFT batch generation cost?
Single-bank generators with validation typically start from around R25,000. Multi-bank setups with accounting and CRM sources, remittance sync-back, and audit logging usually range from R40,000 to R75,000. Teams spending 6+ hours a week on pay-run prep usually see ROI within 2 to 4 months.
Stop Rebuilding EFT Batch Files by Hand
If your pay run still depends on Excel and a hope that the bank portal accepts the file, you are spending money on a problem that has already been solved.
