Leave this blank and keep the box checked if the invoice is still unpaid. The day count then runs through today.
1.5% a month is the national standard for a written commercial term. It is 18% a year of simple interest. Use it only if your contract already says so.
Days after the due date before interest starts. Use 0 if your terms have no grace period.

18% a year is not blocked by an Indiana commercial usury cap. Indiana does not set one. The 25% figure in Ind. Code section 24-4.5-3-201 is for consumer loans. Business credit is outside that article (section 24-4.5-1-202). If the contract is silent, section 24-4.6-1-102 gives you 8%, not this rate.
Can you charge late fees in Indiana on an invoice
Indiana does not have a commercial usury statute I can point you to, and I went looking for one before writing this. Ind. Code section 24-4.6-1-102 is the rule that matters when the invoice is silent: interest on a loan or forbearance is 8 percent a year until the judgment is paid. The 25 percent figure you will see online is Ind. Code section 24-4.5-3-201, and it is a consumer loan finance charge. Section 24-4.5-1-202 says that article does not apply to credit extended primarily for a business, commercial, or agricultural purpose. A freelance invoice to a company is that kind of credit. After you have a judgment, section 24-4.6-1-101 is a different constraint: post judgment interest is 8 percent even if the contract rate before judgment was higher.
What I tell an Indiana freelancer is simple. Put the rate in the estimate if you want 1.5 percent a month. If you did not, the statute gives you 8 percent, not a number you wish you had written. Small claims on the docket after June 30, 2021, is $10,000 under section 33-29-2-4. The 2026 small claims manual from the Indiana courts says the same thing. For the deadline, do not grab the 10 year statute. An unpaid invoice is a written contract for the payment of money, and section 34-11-2-9 gives you 6 years. Prompt payment under section 5-17-5 is about public purchasing, not the studio that has gone quiet. If the amount is over $10,000 you are in a regular civil case, with the same 6 year clock and the same need for a rate that was actually agreed.

Frequently asked questions
No statutory maximum that I can cite for a commercial invoice. Indiana's 25 percent figure is a consumer loan finance charge in Ind. Code section 24-4.5-3-201. Section 24-4.5-1-202 excludes credit extended primarily for a business, commercial, or agricultural purpose from that article. A written 1.5 percent a month on a business invoice is not cut off by that consumer cap. Courts can still refuse a rate that is unconscionable. 18 percent a year is ordinary. 90 percent is a different conversation. If the contract stated no rate, you get 8 percent under section 24-4.6-1-102, not a number you prefer.
Eight percent a year. Section 24-4.6-1-102 says that when the parties do not agree on the rate, interest on loans or forbearances of money, goods, or things in action is 8 percent a year until payment of judgment. That is the whole rule. It is not 1.5 percent a month, and it is not the consumer loan cap. Use 8 percent simple interest for the days the invoice is past due. The calculator on this page can drop the monthly field to that rate.
No, when the credit is primarily for a business purpose. The Indiana Uniform Consumer Credit Code is a consumer statute. Section 24-4.5-1-202 lists the exemptions, and business, commercial, and agricultural credit are on that list. A company hiring you to do the work is not a consumer loan. A neighbor hiring you for a personal project might be closer to the line, and I would not use a consumer exemption as a dare. For a normal B2B invoice, ignore the 25 percent consumer chart and use either your written rate or the 8 percent default.
Ten thousand dollars. Ind. Code section 33-29-2-4 gives the small claims docket jurisdiction over civil actions where the amount sought is not more than $10,000, for cases after June 30, 2021. The Indiana courts' 2026 small claims manual says the same thing. You can waive the excess to stay on that docket, which is usually a bad trade if the excess is real. Attorney fees are hard to get in small claims unless a statute or the contract clearly allows them. If the invoice plus the agreed fee is over $10,000, file it as a regular civil case.
Six years. Ind. Code section 34-11-2-9 says an action on a promissory note, bill of exchange, or other written contract for the payment of money must be started within six years. There is a longer statute for some other written contracts, and older summaries still quote 10 years. An invoice is a contract for the payment of money, so I use the six year section, and the 2026 small claims manual groups notes and contracts for the payment of money at six years as well. Do not miss the shorter clock because a blog remembered the longer one.
Yes, if the contract says so and the fee is not a disguise for a consumer finance charge you are not allowed to take. A flat $50 on a $400 invoice can be easier to explain than a percent that rounds to pennies. It still has to be in the writing before the client is late. A silent contract gives you 8 percent a year under section 24-4.6-1-102, not a flat fee you announce in the third reminder. Pick one method for the next engagement and use it every time.
No. Ind. Code section 5-17-5 is about public purchasing and the state's own payment timing. It does not order a private client to pay your invoice in a set number of days, and it does not add a statutory percent to a design bill. If your client is a government unit, read that chapter before you invent a rate. If your client is a business, use the contract or the 8 percent default. Citing a public purchasing statute in a demand to a private company is the kind of mistake that makes the rest of the letter easy to dismiss.
Only if you promised one. Section 24-4.6-1-102 does not insert a grace period into a silent contract, and there is no commercial statute that forces 10 days of waiting before interest starts. If your terms say net 30 and then 10 days of grace, count from day 41. If they say net 30 and nothing else, the days overdue start the next day. The calculator has a grace field for this. Use the number you printed, including zero. A grace period you mention for the first time in a collection email is not a grace period. It is a concession.
It can drop. Section 24-4.6-1-101 says interest on a money judgment runs at the contract rate, but not above 8 percent a year, even if a higher rate was proper before judgment. If there was no contract rate, the judgment rate is 8 percent. A 1.5 percent monthly rate can be a pre judgment rate and still become 8 percent once the court enters judgment. Build that into the demand. The point of the higher rate is to get paid before you sue, not to keep compounding after you win. Show both numbers if you are explaining the claim.
This is general information, not legal advice. Statutes change and the correct treatment depends on your contract and circumstances. Consult a qualified professional for your situation.
