One subscription, several departments: dividing the cost
Short answer
Automating the split of subscription costs links invoice lines to account and department data under approved rules, and keeps the shared fee apart for a decision. With a few fixed subscriptions a spreadsheet or the allocation in your accounting system is enough. At Syntalith the automation costs from €3,000 net and at 400 lines a month pays back in 2.5 months.

Accounts can be assigned, the shared fee waits
An invoice for an app covers the accounts of sales and of the project team, plus a separate platform fee. The company approved assigning accounts by the user's department, but did not settle how to split the shared fee.
Sales accounts
assigned
The manager checks which accounts landed in their team, linked to the invoice line.
Designers' accounts
assigned
Each line leads to the user data the assignment rests on.
Platform fee
waiting for a decision
Stays apart, with a question to the person responsible for the report rules.
The whole invoice does not land by default in the department of the person whose card paid for it. The sum of department costs and unassigned lines matches the invoice. Once the rule for the shared fee is approved, the report for the same period is produced again, and the earlier version stays available.
Why the report needs data from the billing period
Today's user list differs from the one the invoice covers: someone changed department, or an account was switched off after the month ended. The person preparing the report needs the data and the rule from the billing period. When a department is missing, they see a specific line to clarify with the administrator, without hunting for a difference in the final total.
First check your current system
Microsoft describes cost allocation in Business Central with sources, targets, a validity period and fixed and dynamic allocation bases. If your company uses such features, check with the administrator whether they cover your rules.

What subscription cost automation costs and when it pays back
- Today
- 400 lines × 6 min = 40 h (€1,396)
- With the system, a person checks the output in 15% of the time
- €209
- Model, 1 call per case, Claude Sonnet 5.5
- €2.07

Payback of €3,000
2.5 months
The volume, the time and the checking share are the scenario's assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat. Model: 1,500 input tokens and 300 output tokens per call at Anthropic's rates, converted at the ECB rate of 1.1205 USD per euro on 22 October 2026.
In the scenario each line saves €2.96, so the automation pays back within a year from about 85 lines a month. Below that threshold, stay with a spreadsheet or the feature of your accounting system.
What to order when the split is rebuilt from scratch every month
- 01AppOne shared app and its reporting cycle.
- 02RulesFinance names the rules and the periods they apply to.
- 03DataThe administrator helps find the account data needed for the split.
- 04SummaryThe split with the basis of every line and a list of missing decisions.
- 05VersionsThe previous report stays available when a manager asks about a change.
The way of splitting stays the company's decision. Start the conversation about automating cost allocation with the subscription for which you last had to ask several people about the right department. If licences sit unused, see the article on increasing AI use after buying licences.
