From engagement letters to tax season, Skyline helps your team spend less time on admin and more time serving clients.
Clients can securely sign documents, upload files, and see exactly what's still required through their own portal. And instead of manually entering transactions from a PDF bank statement, Skyline Convert creates a QBO or OFX file you can import directly into your accounting software in seconds.


Skyline Convert
Stop manually retyping transactions from a client's bank statement PDF. Skyline Convert reads it directly and outputs exactly what QuickBooks Desktop or Online expects — built around the banks accountants actually deal with.

Document Collection
Tax Forms, Legal Contracts, ID verification — each client sees a clear checklist of what's required and uploads directly to the correct category. No more guessing which attachment goes where.

Status Tracking
Every client's folder shows what's been submitted and what's still missing, at a glance — across every active client, not just the one you're currently thinking about.

Most signing tools stop at the signature. Skyline covers the whole engagement, from delivery to completed and verified.
One link, not an email chain. You'll know the second an engagement letter is opened, viewed, or signed.
Every client is identity-verified before a signature is binding. Documents are encrypted at every stage, from upload to signed and stored.
Clients get their own portal, no login to create, just a link that shows exactly what's needed, what's signed, and what's still outstanding.
Every client's engagement sits in its own encrypted workspace. Documents, status, history, together. Nothing hiding in email.
Set the signing order once, for joint returns or business partners. Skyline chases the signatures so you don't have to.
Every signed document is sealed and timestamped the moment it's done. If it's ever questioned later, you have the record.
Not just convenient. Legally sound. Every electronic signature Skyline collects is enforceable.
Signatures comply with major global e-signature frameworks, including ESIGN, UETA, and regional electronic transaction laws. Every envelope generates a timestamped Certificate of Completion.
IP address, timestamp, and device captured at every signing event. Tamper-evident and court-admissible.
Built on modern cloud infrastructure with row-level security and encrypted storage. Your documents and client data never leave the platform.
