Interim management software: assignments and timesheets The shortlist in one search.
No ringing round the pool.
The manager declares their own availability and enters their days. Search covers your CVs and interview notes, the client signs the timesheet online, and the invoice goes out without re-keying.
Marvin is software for interim management firms: pool of managers, assignments, timesheets and invoicing in the same tool, hosted in France. Margin is tracked per assignment, per manager and per client, and profiles come out with your logo and colours, in PDF or Word.

One assignment, one pool, one invoice.
Without switching tools.
For an interim management firm, Marvin follows the mandate end to end: the manager declares their availability in their own space, search goes through their CVs and your interview notes, the profile comes out in your branding, then the client signs the timesheet online and the invoice is generated from the approved timesheet.

A repurposed ATS,
spreadsheets around it.
And the assignment in the middle.
Marvin replaces an interim management firm's repurposed ATS and spreadsheets with a real assignment record: client, manager, dates, buy and sell day rates. Managers declare their own availability, profiles come out in your branding, the timesheet is approved online and the margin reads while the assignment runs.

No grey areas.

In their space, the manager only sees their assignments, their days, their documents and their own day rate; the sell day rate and the margin stay on the firm's side. Every action is timestamped and attributed.

Questions from interim management firms.
What software suits an interim management firm that needs a manager portal and timesheet approval?
Marvin brings together the pool of managers, assignments, the manager portal, timesheet approval and invoicing in a single tool. The manager enters their days in their space, your team approves, then the client signs online; the invoice is generated from the approved timesheet. Margin is tracked per assignment, per manager and per client.
Do interim managers really use a portal?
The Marvin manager space opens in a browser through a secure link, with no account or password to remember. The manager declares their availability, enters their days and expenses, and finds their documents there. They are invited automatically as soon as they are placed on an assignment.
Can an interim management firm keep the layout of its presentation profiles?
Yes. In Marvin, the CV and profile summary templates use your logo and colours, and every profile comes out identical, whichever consultant prepares it. An anonymised version takes one click, and export is in PDF or Word.
Can you search for an interim manager by availability, area and sector in Marvin?
Yes. Search filters by availability date, by city with a radius or by mobility area, by sector, by role and by years of experience, and also reads the text of CVs and notes. Desired or current pay can be filtered too. There is no dedicated filter for the size of the companies the manager has worked for: a filterable custom field can hold it.
Does Marvin handle contracts for interim management assignments?
Not today: Marvin does not generate assignment contracts or handle their signature. It covers the talent pool, the assignment, the timesheet signed online by the client, expenses and invoicing. Your contracts stay in your current tool.
How does an interim management firm migrate a talent pool spread across several tools?
A Marvin data engineer audits all your sources (old ATS, spreadsheets, assignment files), merges duplicates and submits every clean-up rule to you before the import. Nothing is loaded without your approval, and your teams keep working in the current tool during the preparation.
Do interim managers submit their expenses in Marvin?
Yes, from their space, once the feature is switched on by the firm: each claim has its category (travel, hotel, meals…) and its receipt, then your team approves it. A claim marked as rebillable is added to the client’s invoice. Marvin does not calculate mileage allowances on the official scale: the amount is entered as an expense.
In an interim management firm, does an office manager who only handles invoicing need a full licence?
They take a licence, like anyone who logs in to Desk, but their role limits what they see and can do, for example assignments and invoicing without candidates. The quote can include licence lines by profile, at their own rate. Managers on assignment and your clients take no licence at all: they use their own space and a link.
Does an interim management firm’s invoicing connect to its accounting tool?
Yes, in two ways: invoicing syncs with Pennylane, and exports as CSV for other accounting software. Invoices come from approved timesheets, rebillable expenses included, with the French legal mentions and the client’s purchase order number. For another accounting tool to connect directly, compatibility is checked during the demo.
Can you schedule a reminder to discuss extending an interim management assignment with the client?
Yes. A reminder is set directly on the assignment, on the chosen date, with a note, and flagged to you on the day; it can also be assigned to a colleague. A custom date field on the assignment, such as an extension review date, can even generate its reminder automatically, without anyone having to think about it.
Do automatic write-ups work for a reference check done by phone?
Only if the call goes through Aircall: it then arrives on the manager’s or contact’s record, with its recording and its transcript when Aircall produces one. Note, for its part, joins Zoom, Meet and Teams video calls as a participant. A face-to-face conversation or a call on a phone not connected to Marvin produces no automatic write-up.
Does the interim manager see the firm’s margin on their assignment?
No. In their space, the manager sees their assignments, the days they have entered, their expenses and their documents, with their own day rate. The rate billed to the client and the firm’s margin stay on the team’s side, visible according to each role’s permissions, and tracked per assignment, per manager and per client.
