Admisol
Integration with Admisol accounting software
Last updated on
Admisol is an accounting package that Tillor supports for sending payment reports. Payment reports are converted to Admisol XML and sent to Admisol automatically or manually.
Installation
- Go to Settings (marker 1 in the screenshot) and choose Integrations.
- Find Admisol in the integration list (marker 2) and open the detail page.
- On the detail page, enter your Company ID and Web Service Key (details from Admisol) and click Install.
Sending automatically
When a payment report changes in substance (for example after linking payments or after Recalculate report):
- Tillor checks whether Admisol is installed for the organisation
- The report is converted to Admisol XML
- The XML is sent to Admisol
During the daily creation (09:00), Tillor works through the missing days from oldest to newest. Each new report is only sent to Admisol once the previous report has received a reply (acceptance or rejection). If sending fails, Tillor stops for that organisation until the next run.
The draft report of the current day is sent to Admisol as soon as it contains a Mollie payment or internal transfer, and after that only again when the booking changes. Cash payments on the draft do not trigger a send. Mollie payments on a draft are booked against the supplier Mollie without a document reference; Admisol books that as an advance ("still to be received"). Refunds that Mollie has not yet withheld appear as a second, separate advance line on Mollie ("still to be withheld"). On the final send, the actual payout with bank costs takes their place, and payments that were not in the settlement move as an advance to the next draft. While the report is a draft, Admisol shows the document reference as PAYR/2026/0275 - Concept; that suffix disappears on the final send. If the report becomes final on the next working day, Tillor sends it again, now with the Mollie settlement, under the same document number and the same booking date.
If an automatic send fails, you get a notification and a line appears on the events timeline of the report.
Sending manually
- Go to Administration > Payment Reports
- Open the report you want to send
- Click "Send to accounting"
Which payments are included?
Only payments with:
- Mollie as provider, or
- Internal Transfer as payment method
Bank account payments are not sent to accounting.
Partial refund (Mollie)
If a linked Mollie payment has been partly or fully refunded, Tillor sends the original payment amount on the payment report of the Mollie settlement in which the payment arrived. The refund appears as a negative line on the report of the settlement in which Mollie deducts the refund (label Terugbetaling). That can be later settlements; multiple refunds each get their own line on the report of their settlement. That way the report matches what Mollie actually pays out. Because refunds are only booked on that settlement day, no extra line on suspense account 499000 (restant saldo) is needed.
Bank costs per Mollie invoice
Mollie withholds its costs from every payout and invoices them once a month. Tillor therefore books the withheld costs per invoice period: each line carries the month for which Mollie invoices the costs, for example Bankkosten 01/2026. A payout in the first days of the month often still contains costs of the previous month; those then appear as a separate line on the same report.
All lines of the same period add up to the amount of that month's Mollie invoice. Lines of the current month stay open until Mollie issues the invoice.
On the supplier Mollie
The withheld costs are not a second cost: Mollie uses them to pay its own invoice. Tillor therefore books them on the supplier Mollie, without a document reference. The cost and the VAT only come in through the Mollie purchase invoice. Each month you match the invoice on the supplier Mollie against the Bankkosten lines of that period; together they are the same size. A correction via a miscellaneous entry is not needed.
Mollie usually withholds the costs of a payment at the moment the payment comes in, even if the payout follows later. A draft report therefore already books those costs per invoice period, and the advance on Mollie is the amount after costs. A card payment that Mollie is still holding has no withheld cost yet: that cost only appears on the report with the payout. Until then the month on the supplier Mollie is not yet complete.
In Admisol, do not match lines of a draft report (document reference ends in - Concept). On the final send Admisol replaces the lines of the report, and matches on those lines may disappear. That can also happen when you resend a final report, even if nothing has changed: check the matches on the supplier Mollie afterwards.
Balance reserve
Mollie sometimes withholds part of the payout as a balance reserve: money you are still owed, but that Mollie temporarily holds back. Because it is neither a cost nor a refund, Tillor books that amount on the supplier Mollie with the label Balansreserve, just like the payout itself. That way it stays visible as an outstanding credit at Mollie instead of on the suspense account. If Mollie later releases the reserve, the report of that settlement shows an opposite Balansreserve line that books the credit off again. You do not have to do anything; on the supplier Mollie the two lines cancel each other out.
Invoices that are already matched in Admisol
Admisol refuses a line on an invoice or credit note that you have manually matched in Admisol against a booking other than the payment report. Tillor then books the lines of that one invoice on the customer without a document reference, so the report still goes through. The amounts and the customer stay the same; you only match the link with the invoice again yourself in Admisol. On the events timeline of the report, the sent XML shows which invoice it concerns.
Accounting parameters
After installation you set the accounting parameters via Settings on the Admisol app (same screen as Company ID and Web Service Key). They include document types for invoices and settlements, the Mollie supplier code, the default general ledger account for invoice lines, and the default department. Missing fields get Tillor default values.
Unknown Mollie payments are booked on the suspense account 499000. Per payment you can also pass department and financial year via Mollie metadata.
VAT regimes
An invoice line with a regime without VAT goes to Admisol with its own tax address profile and tax code. Together they determine which box of the VAT return the line ends up in. The defaults are those of a new Admisol file:
| Regime | Tax address profile | Tax code | Box |
|---|---|---|---|
| Reverse charge (EU services) | EU | vd21 | 44 |
| Reverse charge (co-contractor) | MED | v21 | 45 |
| Intra-community supply | EU | v21 | 46 |
| Export outside the EU | EXP | v21 | 47 |
| VAT exempt | NA | v0 | 00 |
If your file uses other codes, adjust them in the accounting parameters: per regime there is a field for the tax address profile and one for the tax code. You find your file's codes in Admisol under Instellingen > BTW-instellingen > Tax-relaties. The customer record in Admisol keeps its own tax address profile; only the invoice line gets the one from the regime.
