Open source
Some of what we build solves problems other teams have too. We publish it under the MIT licence, so you can use it, read the code and change it.
Invoicing for businesses that bill across currencies and tax systems.
Invoices, estimates and payments in nine currencies, with GST and VAT built in. Customers get branded PDFs and links they can open without an account. The hosted app is free to use, or you can run it yourself.
PHP security fixes for Ubuntu 20.04, where the usual packages stopped.
We built it to patch PHP2Shell on a client's servers. It rebuilds the PPA's own signed, fixed packages, unchanged, for PHP 7.4 to 8.4 on arm64 and amd64. Prebuilt bundles come with build provenance and an installer that simulates before it changes anything.
# Verify where a bundle came from, then dry-run it
gh attestation verify <bundle>.tar \
--repo clarity-tech/php-focal-backports
sudo bash install.sh simulate '<bundle URL>' <sha256>
sudo bash install.sh apply '<bundle URL>' <sha256>We can adapt InvoiceInk to how your business works, or patch the PHP servers you depend on.
We strive for nothing less than the Perfection & Quality.
Understands your business and delivering Future.
