Scaling a DSO: Credit Facilities Built for Multi-Site Growth

Acquiring one practice at a time with one loan at a time will not scale. Delayed-draw facilities and platform debt let dental groups close deals on the seller’s timeline.

Why One-Off Loans Stop Working at Scale

A dentist buying a first practice is well served by a single acquisition loan. A group buying its sixth practice in eighteen months is not. Underwriting each transaction independently means restarting diligence, re-pledging the same collateral, renegotiating covenants, and adding thirty to sixty days to every deal. In a competitive market for practices, that delay costs deals outright.

There is also a structural problem. Each standalone loan carries its own amortization schedule, its own covenants, and its own guarantee package, and the resulting stack becomes progressively harder to manage and harder to refinance. Groups that grow this way often reach a point where the next transaction cannot be financed at all until the whole structure is consolidated.

The alternative is platform financing: a single credit agreement sized to the group’s consolidated cash flow with capacity to fund future acquisitions inside the existing facility. It is how every dental group of meaningful size eventually finances itself, and moving to it earlier than you think you need to is usually the right call.

How Delayed-Draw Acquisition Facilities Work

A delayed-draw term loan establishes a total commitment upfront, part of which funds at close and the remainder of which is available to draw for future acquisitions that meet pre-agreed criteria. The criteria, often called the acquisition box, define practice size, geography, minimum EBITDA, maximum purchase multiple, and post-close leverage limits.

The operational advantage is decisive. When a target falls inside the box, funding is a confirmation exercise rather than a new credit approval, which means you can sign a letter of intent with a thirty-day close and actually deliver. Sellers, who in this market frequently have multiple bidders, consistently choose the buyer they believe will close on schedule.

Pricing on delayed-draw capacity typically includes an unused commitment fee, which is the cost of holding the option. Weigh that against the value of the deals you would otherwise lose. For a group closing four or more transactions a year, the arithmetic is almost always favorable.

Leverage, Covenants, and Add-Backs

Platform lenders size dental facilities on consolidated adjusted EBITDA with pro forma credit for completed acquisitions. Expect a total leverage covenant, a fixed charge coverage covenant typically set around 1.20x to 1.25x, and a limit on how much unrealized synergy you may add back to EBITDA when calculating compliance.

Add-backs are where these negotiations live. Legitimate add-backs include the normalization of a selling dentist’s compensation to a market associate rate, elimination of duplicated administrative costs, and documented supply cost savings from group purchasing. Speculative add-backs for production growth you have not yet achieved will be rejected, and pushing on them damages credibility.

Negotiate covenant headroom for the integration period. A newly acquired practice frequently dips before it improves, particularly if the selling dentist reduces days. A covenant set tightly against a perfect integration will be tripped by a normal one, and covenant amendments cost both money and lender confidence.

Working Capital Across the Platform

Multi-site dental groups have real working capital needs that acquisition debt does not address. Payer credentialing for a newly acquired location under the group’s tax identification number can take sixty to one hundred twenty days per carrier, during which claims flow through transition arrangements and cash collection is slower than steady state.

A revolving line of credit sized against consolidated collections handles this along with supply purchasing, marketing pushes into new markets, and the equipment refresh that nearly every acquired practice needs. Sizing at roughly one month of consolidated collections is a reasonable starting point for a group in active acquisition mode.

Equipment financing remains useful even at platform scale. Rather than drawing acquisition capacity to upgrade an acquired practice’s operatories or add digital imaging, a dedicated equipment facility keeps that spend on the right duration and preserves acquisition capacity for acquisitions.

Positioning for the Eventual Recapitalization

Most dental groups that scale successfully eventually recapitalize, whether by selling to a larger platform, taking private equity investment, or refinancing into institutional debt at a lower cost of capital. Everything you do operationally in the growth phase either supports or complicates that event.

The things buyers and institutional lenders examine are consistent: audited or reviewed consolidated financials, a single practice management platform with clean reporting, standardized employment and associate agreements, documented payer contracts, and evidence that the group performs well without any single dentist. Groups that leave these until diligence lose value and lose time.

Angel Funding Group structures dental acquisition facilities, working capital lines, equipment financing, and real estate loans for groups from two locations to twenty. If your growth plan calls for more than one deal in the next year, the facility should be built for that plan rather than for the next transaction.
