Send Business Checks and Personal Checks Using PostGrid API or Software

PostGrid's checks unlimited API helps you quickly create checks and handles everything from printing to mailing. You don’t need to worry about having the right paper, Magnetic Ink Character Recognition (MICR) ink, MICR printer, stamps, envelopes, or labels. PostGrid works with reliable printers to ensure your checks are printed well. They also take care of putting the checks in envelopes and sending them to the USPS for mailing.

If you need your checks delivered quickly, PostGrid's online check writer can send them by express service, so they arrive in just one day. There are other mailing options too, and the platform picks the best one for you based on your budget and timing. With full printing and mailing services, PostGrid's automation platform takes care of all your payment needs and makes things more efficient. You can easily track where your checks are using PostGrid's dashboard.

Companies can log in to see the status of their checks and when they are expected to arrive. This helps you confirm that the USPS is processing your checks on schedule. If you’ve sent multiple checks at once, all the information is available in one easy-to-use dashboard. You don’t have to enter tracking numbers to check the mailing statuses.

Leverage MICR Font Encoding

You can use MICR technology to protect your checks from fraud and identity theft. Using MICR in-house can be complicated, so many people think it’s better to buy checks from the bank, even though they are expensive and take longer.  

PostGrid’s check writer online works with a trusted printing network to make sure your checks have the security features they need, like the MICR line and font. This way, you can confidently print and mail checks to the right person using our platform.

Integrate With Your Quickbooks Account

Our check printing software allows you to connect our check order features with your accounting or finance software, like QuickBooks. This means you won’t have to enter each check's amount and payee name manually.

Our API integrations let you automatically pull and fill in these details from your CRM when you create checks. You can easily review, approve, and place orders! These integrations offer other advantages, like sending invoices, statements, and bills. Your finance team can use them to automate accounts payable tasks in just a few steps. Plus, you can quickly reconcile your payments without extra effort.

Print Checks With Bank-Grade Security Features

PostGrid works hard to keep your data private and secure. We follow laws like HIPAA, PIPEDA, SOC-2, and GDPR to ensure you can safely send your checks and other items. 

We also provide bank-level security and end-to-end encryption for sending checks. It means it’s just as safe as ordering from your bank, but more affordable and efficient. You don’t need to order checkbook covers anymore!

Attach a Letter With Your Payment Checks

Businesses can include a letter in the envelopes to let payees know what the check is for! You might also want to talk about something else, like renewing a contract, placing a new order, or informing the payee that you only paid part of the amount owed.

Our online checkwriter lets you prepare and send the letter along with the checks in the same envelopes, saving you time and postage. This also boosts efficiency and helps your finance team keep everyone on the same page.

Style Your Checks Using Different Check Designs and Customization Features

Companies can use our built-in check templates from their bank or create their own designs. You can make payments while promoting your brand by adding customizations like your company logo, background images, and marketing messages to your checks. Printing these features on all your checks allows you to market your brand while making payments.

Also, people tend to keep checks, making branding on checks a long-term marketing strategy.

You can easily upload a copy of your check or choose from different templates. It’s simple to add, remove, and edit fields. You won’t have to worry about writing a check or remembering what needs to be included. All our templates are well-designed and have all the necessary fields.

Print Checks on Blank Stock Papers From Scratch at any Volume

A pre-printed check has fixed information already printed on it, like the bank name, address labels, payer details, a note saying it's void after a certain time and the bank account number. The bank routing number is also printed on the MICR line. Sometimes, some variable information, like check numbers, is also pre-printed. The only details you need to fill in are the payee's name, date, signature, and the amount in both numbers and words. You can add this information later by hand or with check writing and printing software.

On the other hand, blank checks are checks that don’t have any information printed on them. They can be thought of as blank check paper. They aren't considered real checks yet because they are just sheets of paper with some security features, like watermarks and microprints. Individuals and companies must print everything, including the bank’s logo, name, address, payer information, the MICR line, and a note saying they are void after a certain time.

PostGrid’s online check writer helps you print your checks from scratch. Hence, even if you don’t have pre-printed check paper stock, you can expect your checks to be ready in no time.
