Every number on this page was run through the same rules NemiRoute uses, so you can check an invoice against it. Amounts are in CAD; your own rates, dates and settings decide your real figures. Not tax advice: confirm rates and rules with your accountant.
Tax on a $100.00 delivery
With Delivery address (recommended) and your GST/HST and QST registration number saved, each order is taxed at the rates of the province it goes to.
| Delivered in | Tax lines | Customer pays |
|---|---|---|
| Ontario | HST 13 % = $13.00 | $113.00 |
| Nova Scotia | HST 14 % = $14.00 | $114.00 |
| Québec | GST 5 % = $5.00 and QST 9.975 % = $9.98 (9.975 rounds up) | $114.98 |
| British Columbia | GST $5.00 (no PST on courier work) | $105.00 |
| Alberta | GST $5.00 | $105.00 |
If the QST number is not saved, a Québec delivery gets only the $5.00 GST and the draft warns "QST is due on deliveries to QC but you have no QST registration number on file, so it was not charged." QST is worked out on the price, not on the price plus GST.
On goods (category Goods & materials) a British Columbia delivery also carries PST 7 % when a BC PST number is saved: $100.00 gives GST $5.00 and PST $7.00.
Rounding: per order line or per invoice
Two Ontario orders of $10.10 each. HST on one is $1.313.
| Rounding | Calculation | Tax |
|---|---|---|
| Per order line | $1.31 + $1.31 | $2.62 |
| Per invoice | $2.626 rounded once | $2.63 |
Prices that already include tax
With Prices already include tax on, an Ontario order priced at $113.00 is $100.00 plus $13.00 HST. The total stays $113.00; only the split changes.
Exempt customers
- A customer who is Tax exempt for everything pays $0.00 tax: a $100.00 Québec order is $100.00.
- A federal department in Québec with only QST ticked under Exempt from pays the $5.00 GST and no QST: $105.00.
- An exemption with a Certificate expires date in the past is ignored. A $100.00 Ontario order is taxed $13.00 again, with a warning.
Credit note on an invoice with tax
A Québec invoice for $114.98 (price $100.00, GST $5.00, QST $9.98) gets a $50.00 credit note. The amount you enter is the total; its tax reverses the invoice's tax in the same proportions:
| Part | Amount |
|---|---|
| GST reversed | $2.17 |
| QST reversed | $4.34 |
| Credit before tax | $43.49 |
| Credit note total | $50.00 |
A credit larger than the invoice never reverses more tax than the invoice carried.
Due dates and early-payment discounts
For an invoice dated 26 October 2026:
| Payment terms | Due |
|---|---|
| Net 15 | 10 November 2026 |
| Net 30 | 25 November 2026 |
| End of month | 31 October 2026 |
| Net 30 EOM (end of month plus 30 days) | 30 November 2026 |
| Due on the 10th of next month | 10 November 2026 |
| Due on receipt | 26 October 2026 |
With 2/10 net 30 on a $1,000.00 invoice, the customer pays $980.00 by 5 November (the discount is 2 % of the total, tax included, $20.00). On 6 November the offer is gone and the full $1,000.00 is due on 25 November. A paid-early invoice gets an early-payment credit note for the discount.
Aging buckets
On 26 October 2026 an invoice is placed by how many days past its due date it is:
| Due date | Days late | Bucket |
|---|---|---|
| 5 November 2026 or 26 October 2026 | 0 | Not yet due |
| 25 October or 26 September 2026 | 1 to 30 | 1-30 days |
| 25 September or 27 August 2026 | 31 to 60 | 31-60 days |
| 26 August or 28 July 2026 | 61 to 90 | 61-90 days |
| 27 July 2026 and older | 91 or more | Over 90 days |
How one payment is spread
Three open invoices: INV-2026-0001 due 1 October ($200.00), INV-2026-0002 due 15 October ($100.00), INV-2026-0003 due 31 October ($300.00).
- A $350.00 payment is spread oldest due date first: $200.00 + $100.00 + $50.00 on the third, which keeps $250.00 due.
- A $700.00 payment pays all three ($600.00) and the extra $100.00 stays as customer credit on the account.
- If you pick the invoice yourself, only that invoice is paid (never more than it owes).
Credit on account pays a new invoice automatically when Use credit on account automatically is on, never more than the amount due or the credit held: $40.00 of credit on a $113.00 invoice leaves $73.00 due; $40.00 of credit on a $25.00 invoice pays it and keeps $15.00.
A customer statement
Statement for 1 to 31 October 2026. The customer owed $200.00 before the period.
| Date | Line | Amount | Balance |
|---|---|---|---|
| 1 Oct | Opening balance | $200.00 | |
| 5 Oct | Invoice | +$113.00 | $313.00 |
| 12 Oct | Payment | -$200.00 | $113.00 |
| 20 Oct | Credit note | -$11.30 | $101.70 |
The closing balance, $101.70, is what the customer owes on 31 October.
Credit limits
A customer has a $5,000.00 limit, $3,200.00 of open invoices, $900.00 of delivered or in-progress orders not yet invoiced and $300.00 of credit on account. Exposure is $3,200.00 + $900.00 - $300.00 = $3,800.00.
- A new $1,000.00 order makes $4,800.00: under the limit, so nothing happens.
- A new $1,500.00 order makes $5,300.00: over the limit, so your Credit limit rule acts (warn, hold for approval or refuse).
- A rule that triggers after 15 days overdue acts on the customer's next order once an invoice is 15 days or more past due, whatever the amount.
Your own NemiRoute bill
On Subscription, a plan can charge per active driver or active vehicle over an included number. Example: $149.00 a month, 5 active drivers included, $12.00 per extra driver, 8 active drivers, Ontario:
| Line | Amount |
|---|---|
| Plan | $149.00 |
| 3 extra drivers x $12.00 | $36.00 |
| Before tax | $185.00 |
| HST 13 % | $24.05 |
| Charged | $209.05 |
Billed yearly, the 3 extra drivers are charged for 12 months ($432.00) on top of the yearly price. A $1,490.00 yearly price against 12 x $149.00 shows Save 16.7% vs monthly.
