Outcomes
What dedicated, accountable teams produce over time.
"We operate in a space where accuracy and documentation are not optional, so my concern with any outsourced arrangement was whether the work would hold up under scrutiny. It has. Assivo's team took on multiple finance and accounting functions for us and worked to our standards from the start, with US management we could actually reach when something needed attention. The work is documented, the handoffs are clean, and the output has been dependable enough that we stopped thinking about it. As we have grown, they have grown with us. That has let our internal team spend its time on the things only our internal team can do."
Abacus Global Management
"We started with Assivo in one area and kept expanding because they earned it. What began as a defined scope of back-office work grew into several business and data processes, and each time we handed something over, it came back running better than it had before. The part that matters most to me is consistency. We are not re-training a new team every quarter or chasing status updates. The same people have been on our account, they understand how we operate, and they hold themselves accountable for the work. That is rare in this category. They have been a genuinely reliable partner to us, and I do not use that word loosely about vendors."
DTiQ
"Assivo runs our data infrastructure and data operations at significant scale. That is not work you hand to just anyone - the volume is real, the accuracy requirements are real, and when it goes wrong it shows up everywhere downstream. They built a team around our operation and kept it stable, so the institutional knowledge stayed with us instead of walking out the door every few months. When we needed to expand scope, it was a conversation, not a new procurement process. They have been a real partner through a period of significant growth, and they are one of the few outside teams I would recommend without hesitation."

Your Operation May Be Different. That's Fine.
Most of our work is bespoke. The categories above reflect our core expertise, but we are built for custom requirements. If your operation shares the fundamentals - high volume, real stakes, and the need for human follow-through - we should talk. We become part of your workflow: trained on your systems, following your processes, and accountable for the results.
Common Questions
Both. Teams are trained on your DTD or schema and validated output is delivered to your specification, alongside standard formats like ePub 3, JATS, and DITA.
Complex elements are converted by hand where automated tools fail, with side-by-side verification against the source. Fidelity issues are flagged, not silently approximated.
Yes. Backlist programs are scoped as phased projects with per-title quality gates, so you approve early batches before the full run proceeds.
Yes - EPUB Accessibility 1.1 and WCAG conformance, including alt text workflows, reading order verification, and accessibility metadata.
A US-based engagement manager owns the program end to end, with documented QA standards and per-batch acceptance reporting.
