That's why all of our work is open source. Agencies are free to reuse work we perform for other partners. Often, agencies will still need help implementing it for their specific needs, but we don't charge for the work we've already done. For instance, we've helped a couple agencies get regulations on the eRegulations platform https://eregs.github.io/ and many are using the Draft U.S. Web Design Standards to speed up development https://standards.usa.gov/.
