Your client invites you. You see everything, read-only.
No data entry on your side, no shared passwords, no exports emailed back and forth. The contractor stays in control and can remove access at any time.
The compliance numbers, already added up.
T5018 totals, already added up
Markup flags every subcontractor who passes $500 in a calendar year and keeps a running total. No more rebuilding the subcontractor summary from a shoebox in June.
HST, GST, and PST, collected and paid
Tax is recorded by province and stored separately from the base amount, so the numbers for the return and the Input Tax Credits are already split out.
Holdback as a real liability
Statutory holdback is tracked as its own line, not buried in revenue, so the balance sheet reflects what is actually owed and when it releases.
Export to your workpapers
Invoices, expenses, and subcontractor payments each export to CSV, ready to drop into your bookkeeping software or working file.
Recommend it once. They run cleaner all year.
Markup is the Canadian-trades compliance bundle. When your clients use it, the records you need arrive in shape, and they get the welcome offer of 50% off their first three months on a monthly plan. No code for you to hand out, it applies on its own.

Questions accountants ask
Do I pay for Markup as an accountant?
No. Accountant access is included in your client's Plus plan. Your client invites you by email, you confirm with a one-time code, and you get a read-only view. There is no separate accountant subscription and no card required from you.
Can I see more than one client?
Yes. Every client who invites you appears under one login. You switch between clients from a single dashboard rather than juggling separate accounts or passwords.
Is my access read-only?
Yes. You can view and export your client's invoices, expenses, and subcontractor records, but you cannot edit or delete their data. The contractor stays in control and can remove your access at any time.
Does Markup file my clients' HST or T5018 returns?
No. Markup records the numbers (HST, GST, and PST collected and paid, T5018 totals once a subcontractor passes $500 in a year, holdback as a separate liability) and gives you CSV exports. Filing the returns is your job. Markup gets you the figures, cleanly, without chasing receipts.
What can I export?
Invoices, expenses, and subcontractor payments each export to CSV per client, so you can drop them straight into your workpapers or bookkeeping software.
