Pricing per API request
A tool to estimate the cost of the input invoice lookup API. Fixed tiers — enter invoices per month, number of sync requests, number of read requests, and choose whether to fetch detail to see the total cost.
Parameters
Unchecked (header only): general invoice info — seller/buyer, tax code, invoice serial & number, issue date, totals (pre-tax / tax / payable).
Checked (with detail): line items (goods/services) — item name, unit, quantity, unit price, amount, and per-line tax rate (each invoice ×1.5).
Checked (with detail): line items (goods/services) — item name, unit, quantity, unit price, amount, and per-line tax rate (each invoice ×1.5).

Per-invoice fee (tiered)100.000đ
Read fee (list/detail) (1.000đ × 0)0đ
Total / month110.000đ
Average effective unit price: 2.200đ / invoice
| Tier | Invoices | Unit price | Amount |
|---|---|---|---|
| 1 – 100 | 50 | 2.000đ | 100.000đ |
| 1.001 – ∞ | 0 | 100đ | 0đ |
How it is calculated
Cost = sync fee + per-invoice fee (regressive/volume-based tiered pricing) + list/detail read fee.
1. Per-invoice fee (sync & fetch detail endpoints)
| Tier (up to invoice #) | Unit price / invoice |
|---|---|
| 100 | 2.000đ |
| 500 | 500đ |
| 1.000 | 250đ |
| > 1.000 (excess) | 100đ |
- Sync fee: 10.000đ / sync (each window ≤31 days = 1 request).
- Fetch detail: ×1.5 per invoice.
- Applies to sync and on-demand fetch detail.
2. Read fee (invoice list & detail)
- Invoice list and Invoice detail: each request = 10% of the sync fee = 1.000đ, even when read from stored data.
3. Free of charge
- Registration / account management, tracking sync progress, usage reconciliation.
Only new invoices are charged
Re-syncing the same period is not re-charged — the system prevents duplicates and only charges for new invoices. Read requests are counted per endpoint (see Usage reconciliation).
