Suing for an Unpaid Invoice in Saskatchewan Small Claims Court

A client received the work, acknowledged the invoice, and stopped returning your calls. This is the most common scenario in Saskatchewan small claims court: a liquidated debt where the amount is clear and the evidence is straightforward. Here is how to move from frustration to a filed claim.

Start with a Formal Demand Letter

Before filing anything, send a written demand. Saskatchewan law does not technically require it, but judges expect it, and a well-drafted demand letter often resolves the matter without court.

Your demand letter should include:

• The legal names of both parties (your business and the debtor — if they are incorporated, use their corporate legal name, not just the trade name)
• A chronological summary of the work performed and the invoice details
• The total owed, including any contractual interest
• A clear deadline — 14 calendar days is standard
• A statement that you will file a small claims action if payment is not received

Send it by registered mail so you have a Canada Post delivery confirmation. This record becomes evidence later.

Verify the Debtor's Legal Name

This step prevents the single most common enforcement problem. If you sue "Dave's Landscaping" but the actual registered entity is "1234567 Saskatchewan Ltd. operating as Dave's Landscaping," your judgment may be unenforceable against the real entity.

Run a search through the Information Services Corporation (ISC) corporate registry at isc.ca. An official Corporate Registry Profile Report confirms the exact legal name, registration status, registered office address, and directors. The search cost is a recoverable court disbursement if you win.

For sole proprietors, name the individual plus their trade name: "David Smith operating as Dave's Landscaping."

Filing the Claim

Complete the Form A Summons at the Provincial Court registry. For an unpaid invoice claim, the structure follows a standard pattern:

• Paragraph 1: Your legal name and contact details
• Paragraph 2: The defendant's verified legal name and address
• Paragraph 3: The work performed, the invoice date, the agreed price, and the fact that payment has not been made despite the demand
• Paragraph 4: Confirmation that you sent a demand letter and the deadline passed without payment
• Paragraph 5: The total claimed — principal, pre-judgment interest (contractual rate or the statutory rate under The Pre-judgment Interest Act), the C$100 filing fee, and any service costs

The filing fee is C$100. File at the Provincial Court registry closest to where the work was performed or where the defendant resides or does business. Saskatchewan's monetary limit is C$50,000, so most small business invoice disputes fit comfortably.

Building Your Evidence Package

Unpaid invoice claims live or die on documentation. Organize a binder with:

• The signed contract or written quote (even text messages confirming the scope and price count)
• The invoice itself, with dates
• Proof the work was completed — delivery receipts, completion photos, client sign-offs, emails acknowledging receipt
• Communication trail — emails, texts, and voicemails asking for payment
• Your demand letter and the Canada Post delivery confirmation
• Bank or accounting records showing no payment received
• Your pre-judgment interest calculation

Tab each exhibit and create a chronological index. Judges process dozens of cases; a tidy binder communicates credibility before you say a word.

At the Hearing

Present your case in order: what was agreed, what was delivered, what was invoiced, what was demanded, and what was ignored. Point the judge to each document as you reference it. Keep it factual — the numbers do the work.

If the defendant does not appear and has not filed a Form B Reply, the judge can grant default judgment for the full amount claimed.

After the Judgment

A judgment is a piece of paper — it does not put money in your account. If the debtor pays voluntarily, you are done. If not, you need to pursue enforcement through the Court of King's Bench: register the Certificate of Judgment, then use garnishment, asset seizure, or property liens to collect.

The Saskatchewan Small Claims Filing Guide includes an evidence index template, a service tracker, and a deadline calendar built for exactly this scenario — turning a stack of invoices and text messages into an organized court-ready case.
