A cash management guide to making your money work for you

The gap between managing your cash manually and letting a rule do it for you is measured in hours, missed yield, and the quiet stress of one more thing you’re supposed to remember. Here’s how businesses across three industries set up rules that match the way they actually operate.

Many agencies, consultancies, and firms that collect their revenue in irregular chunks use the Profit First method. It’s one of the more effective frameworks for becoming profitable from day one, setting aside money for the future, all while paying yourself along the way. 

The general approach is to allocate every dollar to one of the following five categories:  Operating Expenses, Tax, Profit, and Owner’s Pay. By setting up a percentage-based auto-transfer rule, you can distribute incoming funds across those accounts the moment they arrive.

For example, revenue may land in a primary account. A rule triggers on deposit and splits it: 

• 30% to Operating Expenses
• 15% to Tax
• 10% to Profit
• 5% to Owner’s Pay
• 40% staying put for payroll and overhead

The percentages are yours to calibrate, and a single rule can distribute to up to 20 accounts. Allocation happens on the day the money arrives, not three days later when someone gets around to it.

Anyone who’s tried running Profit First manually knows where it breaks down. You skip one cycle because you’re on a client site. You skip another because it’s month-end. By Q2, the system exists on a spreadsheet and nowhere else. Automation removes that failure mode entirely. The rule runs whether you’re in the office or not, and the discipline holds because it doesn’t depend on your calendar.

Startups typically hold two to three months of operating expenses in checking accounts and don’t think much about the rest. But a large balance in a checking account earning nothing when it could be in Treasury generating yield is a cost most founders don’t see on any statement.

Siddharth Dhulipalla, co-founder and CEO of Hathora, a multiplayer game server platform, built his cash management around this problem. His main operating account holds two months of expenses. A backup account holds one month as a safeguard. And over 90% of Hathora’s funds sit in Mercury Treasury. Auto-transfer rules maintain the minimum balance in each operating account and keep the bulk of capital invested.

Dhulipalla calls this his favorite feature of Treasury: The rules guarantee sufficient capital for daily operations while the majority of funds stay earning yield. “This feature allows me to rest easy, knowing that Hathora’s financial operations are efficient, secure, and strategically aligned with our long-term objectives,” he said, adding that the setup freed him to focus on growth instead of monitoring balances.

That three-tier structure extended Hathora’s runway by three months. For a VC-backed startup, three months of additional runway from a rule that took minutes to configure is hard to argue with.

Tyler Bliha, founder of Abode Money, runs a similar structure and treats it as part of his product architecture. Surpluses shift into Treasury through automated sweep rules, and the Treasury balance itself earns yield while his team stays focused on the product. “Everything posts, tags, and rolls up automatically, so even during peak weeks the books stay audit-ready,” Bliha says, noting that they “don’t have to slow down decision-making to wait for finance to catch up.”

Eric Wu at Sobo Foods, where he’s the only full-time employee, uses the same setup while running a frozen dumpling brand across grocery stores and trade shows from coast to coast. “Mercury is the first time that I’ve used Treasury,” Wu said. “It just made it really easy and it’s the closest thing to free money that I’ve found in business.”

A few mechanics worth noting: Auto transfers from Treasury are limited to two per month, and scheduled dates must be at least seven calendar days apart. Rules on a schedule run at 6:00 AM PT on business days. If a scheduled date falls on a weekend or holiday, the transfer executes on the preceding business day. If there aren’t enough funds for a scheduled rule, Mercury skips it, sends you a notification, and the rule continues running as normal on its next cycle. 

Ecommerce founders live inside a cash conversion cycle that punishes loose controls. Inventory orders, ad budgets, and supplier payments all pull from the same pool, and the timing gaps between spend and revenue create pressure that compounds during seasonal surges.

Andrés Ornelas Vargas, founder of Verve Market, runs his platform on a structure built around this tension. His team uses credit cards locked to specific channels and campaigns, with custom spending limits per card. But the layer underneath that discipline is the cash management: keeping operating funds liquid for partner payouts while idle cash earns yield in Treasury, with Bill Pay scheduling and approval rules aligning financial workflows to payout cycles.

The auto-transfer rules that support this kind of setup come in three flavors:

Together, these rules turn a volatile cash cycle into a structured system, automatically routing money where it needs to go so inventory, growth, and operations stay funded without constant manual oversight.

The setups above look different on the surface. A Profit First percentage split, a Treasury sweep with balance thresholds, an inventory ring-fence with weekly fixed amounts. But they all start in the same place: the auto-transfer rules tab in your Mercury dashboard. You can pick from four templates, build a custom rule from scratch, or describe what you want in plain language and let Mercury suggest the right setup.
