Where your deal-closed-to-billing hand-off typically breaks

The first or a renewal payment fails and the subscription goes past due, unpaid or cancelled. The account owner sees a healthy customer and does not call; the customer is surprised by a cut-off, or keeps access for free.

Why it happens. Failure is handled inside billing (automatic retries, then a setting that decides what happens), and the CRM learns of it only if a status is sent back (our reading).

Usually fixed by: Finance operations (collections), with sales or customer-success operations (visibility to account owners).
Kind of break, one of six: Return path: does what the next tool did get back to the first?

The way back is missing or partial: the first payment is shown but a cancellation is not, or nothing at all. The account stays "closed won" forever, and the CRM cannot show who is active, past due or cancelled.

Why it happens. The return path is a separate setup with its own settings. In some tools the status is only set when the connection is configured for it, and a status built on one payment event misses invoices paid another way (a trial, a credit, a payment recorded outside the tool).

Usually fixed by: CRM admin or sales operations, with finance operations.

The status in the CRM is behind because messages from billing arrived in a different order, arrived twice, or were missed during an outage. Reps chase customers who have paid, or relax about customers who have cancelled.

Why it happens. In some tools, status messages can arrive out of order or more than once, and delivery is retried only for a limited time. A receiver that applies each message as it arrives ends up with an old status.

Usually fixed by: Whoever runs the connection (CRM admin or an engineer), with sales operations.

After signature, the price, quantity or term is changed in the CRM or in billing (a discount agreed by email, extra seats), but the signed document is not updated, or the reverse. Three records now disagree, and it surfaces at the first invoice or the renewal.

Why it happens. In some tools a fully signed document is locked, so later changes are made somewhere else, and nothing links the change back to the document (our reading).

Usually fixed by: Finance operations (billing side), with sales operations; the document itself belongs to whoever manages contracts.

The invoice total differs from the deal or contract by a few cents, or by a whole unit in a currency without cents. Occasionally the invoice is in a different currency than the contract, or an amount is out by a factor of 100. Small gaps eat time and the big one is easy to miss among them.

Why it happens. Tools round at different points (per line, per invoice, tax on its own), currencies have different smallest units, and in some tools one price can exist in several currencies with a default used when none is passed.

Usually fixed by: Finance operations.

An issued invoice has an amount, term or detail that differs from the deal. People void it and issue a new one, or issue a credit, so the CRM, the contract and billing now hold different versions. In some countries, rules also apply to how an invoice may be corrected.

Why it happens. Once issued, most of an invoice is locked in some tools, and a correction is a separate document (credit or replacement) that the other tools do not see.

Usually fixed by: Finance operations, with whoever is responsible for accounting (for the rules).

A customer adds seats or changes plan part-way through a term. Billing works out a part-period credit and charge that no one quoted; the credit may sit as a balance, and the extra charge may wait for the next invoice. The CRM shows the new full amount while finance sees an odd invoice.

Why it happens. In some tools partial periods are calculated by the tool's own rules (for example to the second), whereas the deal records only the new annual number. Rules differ between tools.

Usually fixed by: Finance operations, with sales operations (how mid-term quotes are produced).

The same customer has two records in your billing tool, each with its own payment method, subscriptions and invoices. Payments, credits and renewals are split between them, and the CRM points at only one.

Why it happens. The hand-off creates a new billing customer each time it runs (a retry after a timeout, a second deal, a checkout link) instead of first looking for an existing one by a stored ID. In some tools two customers cannot be merged afterwards.

Usually fixed by: Finance operations, with whoever maintains the connection.
