AI across bookings, instalments and the money actually due
What can AI do for a developer’s sales and collections?
The instalment engine reconciles to the paise, delay interest accrues with grace, and the receipt waterfall is oldest-due-first. Those are rules, not predictions. The copilot reads their output and tells you which units are behind and by how much.
Every figure in a LekhaPro answer is computed before any model sees it. A router picks the deterministic engines the question needs, those engines read your posted books and return a structured snapshot, and only then is the language model given that snapshot and told to write the reply. Switch the model off and an on-device narrator writes the same answer from the same numbers.
For a developer the useful AI question is never "what might happen" — it is "who owes me what, right now, across every tower".
Who does what
| Step | Who does it | Can the model change it? |
|---|---|---|
| Read the posted ledger | Deterministic engine | No |
| Compute the figure | Deterministic engine | No |
| Choose which engines to run | Router | No |
| Write the sentence | Language model | Wording only |
| Propose an action | Named, validated tool | Drafts it; you approve |
| Write to your data | Existing audited mutation | Never unattended |
What it does here
- Summarises collections due, overdue and accrued interest by project
- Answers unit-level availability and booking-status questions
- Surfaces which payment plans are slipping
The boundary
- Buyer-portal depth is limited — check what it covers before promising it to customers.
- Delay interest and waivers follow configured rules; AI does not decide a waiver.
Questions
What can AI do for a developer’s sales and collections?
The instalment engine reconciles to the paise, delay interest accrues with grace, and the receipt waterfall is oldest-due-first. Those are rules, not predictions. The copilot reads their output and tells you which units are behind and by how much.
Does the AI ever calculate the numbers itself?
No. A deterministic engine computes every figure from your posted books and hands the model a structured snapshot; the model writes prose about it. Turn the model off and an on-device narrator produces the same answer from the same numbers — which is the test worth applying to any AI accounting claim.
Can it change my data?
Only through named tools bound to existing audited mutations, argument-validated before they run, and every tool that writes carries an approval requirement. Nothing bypasses the permissions your user account already has, and every write is logged like any other.
