When the retainer doesn’t automatically fit: a common everyday situation
Imagine this: your new client pays a retainer into the agency accounts, several projects run in parallel and partial invoices are due at month‑end. In accounting there are no clear allocations, partial usages are agreed manually, and general payment statuses get lost in the inbox. Result: time loss, lack of clarity towards the client and time‑consuming follow‑up work.
Why keep retainers as separate open items (OP)?
- Clarity: Prepayments are kept separate from receivables and are not mixed with ongoing invoices.
- Traceability: Every posting and partial clearing remains documented.
- Automation potential: Recurring partial allocations can be standardized without relinquishing control.
What you can achieve in Debentra
Debentra enables you to map retainers and prepayments as independent open items, post partial usages from them against invoices, create automated clearing rules and store all booking documents in an audit‑proof manner. Crucial: approval stays with the user — automatic suggestions can be reviewed before anything is finally posted or a payment reminder is sent.
Concrete benefits (brief)
- Fewer manual matchings through targeted OP structure (PRO functionality reduces allocation effort).
- Audit‑proof document storage and optional integration into accounting (PREMIUM).
Step‑by‑step: Retainers and prepayments in Debentra
1. Create the retainer as its own open item
- Create a new open item: OP type = "Retainer" or "Prepayment"; record the customer, amount, currency and payment date.
- Enter the purpose of use and project reference (e.g. project name or service period) so that later partial usages are clearly traceable.
- Optional: record payment method and bank reference if the receipt has already been posted.
2. Post the payment receipt and mark the OP
Import bank statements or record the payment manually. Assign the payment receipt to the previously created retainer OP. Debentra will then mark the OP as covered but keep it as an open prepayment so that later partial usages can be cleanly allocated.
3. Post a partial usage against an invoice
- Create an invoice or import it into Debentra and assign it to the corresponding customer/project.
- When assigning a payment choose, instead of a full payment, the option "Partial settlement with retainer"; enter the amount to be taken from the retainer.
- Debentra reduces the retainer OP by the partial amount and marks the invoice accordingly as (partially) paid. The booking lines show origin (retainer OP) and target (invoice number).
4. Instalment plans and recurring partial consumptions
For retainers with regular consumption cycles (e.g. monthly hours reconciliation) set up instalment plans or recurring booking orders in Debentra. These automatically create the partial charges as suggestions; approval remains manually controllable so accounting can check each month before the charge is executed.
5. Use automatic write‑off rules sensibly
- Define rules such as: "Automatically apply retainer to invoices of the same project" or "Automatically write off when remaining amount < X EUR".
- Use a review option: rules can produce suggestions that are only approved after review. This preserves the control point.
- Prioritise rules: e.g. first settle older outstanding invoices, then project‑related ones.
6. Document accounting vouchers in an audit‑proof manner
Each settlement in Debentra generates accounting vouchers that are automatically linked with related documents (proof of payment, invoice, internal approvals). The key aspects:
- PDF backups of invoices and payment receipts are attached to the open item.
- Change log (audit trail) documents who made or approved which booking and when.
- Export functions provide the vouchers for handover to the external accounting system or to the accounting integrated in Debentra (PREMIUM).
Practical example: agency with a monthly retainer
A digital agency agrees a monthly retainer of 3.000 EUR with a client. The client pays 9.000 EUR at the start of the quarter. Procedure:
- Create a retainer open item for 9.000 EUR and post the payment.
- For each month create service records and issue the corresponding invoices for the respective due partial amounts.
- When creating invoices Debentra automatically proposes the partial settlement from the retainer. Accounting reviews the suggestions, approves them and Debentra reduces the retainer open item month by month.
- At the end of the quarter the retainer is partially or fully consumed; all accounting vouchers are stored audit‑proof and exportable.
Typical mistakes and how to avoid them
- Mistake: mixing retainers with general customer credits. Tip: Always use open item type "Retainer" and maintain project/service references.
- Mistake: running automatic rules without a review mechanism. Tip: configure rules as suggestions and require approval by accounting.
- Mistake: not attaching vouchers. Tip: secure payment receipts, approvals and related invoices directly on the open item – this saves queries and audit effort.
Organisational recommendations
- Establish standards: consistent naming of retainer open items, defined review paths and responsibilities for approvals.
- Control rhythm: monthly reconciliation between project management and accounting on retainer consumption.
- Documentation requirement: every partial consumption should be linked to proof of service/time tracking.
How Debentra concretely simplifies the work
Debentra offers the features that model this process: open‑item types for retainers/prepayments, partial payments/installment plans, automatic allocation logics (PRO to reduce manual assignment) and audit‑proof document management. The PREMIUM edition extends this with deeper integration into accounting workflows for the export of booking documents. The system remains self‑hosted – your data stays on your infrastructure, and approvals are made by your contacts.
Conclusion and quick start
Representing retainers as separate open items provides clarity, reduces reconciliation effort and ensures traceable booking documents. Debentra supports this workflow from creating the prepayment through partial reconciliations to audit‑proof filing of documents – without relinquishing control. For agencies and consultants, this is a pragmatic way to manage recurring prepayments cleanly.
