Supergood | Timeslips API
Programmatically access clients, matters, time and expense slips, pre-bill review, and invoicing from Sage Timeslips with a stable REST API. Supergood builds and operates production-grade, unofficial Timeslips integrations so your team can automate time & billing workflows without heavy custom engineering.
Plain English: Timeslips is timekeeping and billing software for law firms. It helps attorneys and staff capture time and expenses, apply rates and billing arrangements, review pre-bills, issue invoices (including LEDES e-billing formats), record payments and trust transfers, and report on profitability. An unofficial API lets you pull clients, matters, rates, slips, pre-bill status, invoices, and payments—and push new time entries, write-downs, approvals, trust movements, and invoice delivery.
For a tech company integrating with Timeslips—especially a legaltech startup fitting into an iManage workflow—this means you can sync matter and client rosters from Timeslips to your platform, auto-capture time from iManage document/email activity into slips, drive pre-bill approvals from your case or workflow tool, generate LEDES-compliant invoices, and publish PDFs back into the appropriate iManage workspace. You can build features like activity-based time capture, matter-level profitability dashboards, automated write-down rules, and unified billing queues that sit alongside the DMS your lawyers already use.
What is Timeslips?
Timeslips (https://www.timeslips.com/) is a time and billing platform widely used by law firms and professional services organizations. It supports granular time and expense capture, flexible rate management, pre-bill review workflows, invoicing (including LEDES formats), payments, and trust/retainer accounting.
Core product areas include:
- Time & Expense Capture (slips, activity/task codes, timers)
- Rates & Billing Arrangements (hourly, flat fee, contingency, custom rates by timekeeper/matter)
- Pre-Bill Review & Adjustments (write-downs, narratives, approvals)
- Invoicing & E-Billing (PDF and LEDES 1998B exports, email delivery)
- Payments & Trust/Retainer (receipts, trust transfers, allocations)
- Reporting & Analytics (realization, utilization, WIP, A/R, profitability)
- Integrations (accounting systems, document management workflows)
Common data entities:
- Clients (organizations/individuals, billing profile, contacts)
- Matters/Projects (client, responsible attorney, billing arrangement, rates, status)
- Timekeepers (attorneys/staff, roles, default rates)
- Slips (time and expense entries with codes, rates, amounts, billable flags)
- Activity & Task Codes (standardized classification for work performed)
- Billing Cycles & Pre-Bills (grouped WIP for review and approval)
- Invoices (finalized bills, formats, delivery status)
- Payments & Trust Accounts (receipts, transfers, balances)
- Users/Roles (permissions, approval rights)
- Audit Events (who changed what, when)
The Timeslips Integration Challenge
Law firms rely on Timeslips daily, but turning its desktop- and portal-centric workflows into API-driven automation presents challenges:
- Data modeling complexity: Rate hierarchies (timekeeper/matter/client), billing arrangements, and write-downs must be applied consistently during calculation.
- Pre-bill lifecycle: WIP collection, narrative edits, approvals, and adjustments span hours to days and require asynchronous handling and auditability.
- E-billing formats: LEDES field mapping, task/activity code sets, and client-specific requirements need normalization to avoid rejection.
- Trust & payments: Retainer balances, allocations to invoices, and split payments need accurate sequencing and safeguards.
- DMS alignment: Mapping matters and documents between Timeslips and iManage workspaces requires reliable identifiers and cross-system references.
- Authentication & sessions: Headless automation must maintain secure sessions and respect role-based permissions and approvals.

Frequently Asked Questions
Q: Which Timeslips modules can this integration cover?
Supergood supports workflows commonly used for legal billing, including Clients & Matters, Time & Expense Slips, Billing Cycles & Pre-Bills, Invoices & LEDES Exports, Payments & Trust, and Reporting/Audit, subject to your licensing and entitlements. We scope coverage during integration assessment.
Q: How do you align Timeslips data with iManage workspaces?
We support mapping by client/matter identifiers and can store iManage workspace and document references on slips, pre-bills, and invoices. Attachments (e.g., PDF invoices) can be published back to the correct iManage workspace for unified matter files.
Q: Do you support pre-bill review and approvals?
Yes. We can generate pre-bills, synchronize queues and statuses, apply write-downs and narrative edits, and capture approvals with normalized audit records. Long-running operations are handled via polling or webhooks.
Q: Can you generate LEDES files?
Yes. We produce LEDES 1998B alongside PDF invoices and support configurable mappings for activity/task codes, timekeeper IDs, and client requirements to minimize rejection risk.
Q: How are rates and billing arrangements handled?
We apply the platform’s rate hierarchy (timekeeper/matter/client) and billing arrangement (hourly, flat, contingency) consistently, preserving raw calculations while exposing normalized totals and adjustments.
Q: Do you support trust and payment allocations?
Yes. We can record payments, allocate trust balances to invoices, and enforce sequencing rules to prevent over-application, with complete audit trails.
